From Rockford Register Star (1/31/2012 10:03PM):
BYRON — Operators at Byron Generating Station terminated the Unusual Event at 8 p.m. today, after the return of power to Unit 2.
“Our diesel generators performed as expected in providing continuous electricity to the unit during the Unusual Event. Plant teams will now focus on a safe and measured approach to returning Unit 2 to the electrical grid,” said Byron Station Site Vice President Tim Tulon.
Station personnel are in communication with local, state and federal officials, including the U.S. Nuclear Regulatory Commission on the facility’s status.
The Unusual Event, which was declared Monday, is the lowest of the four emergency classifications as established by the NRC.
Byron’s Unit 1 continues to safely supply electricity to customers.
Exelon Nuclear officials say an equipment failure in a switchyard near the plant triggered the automatic shutdown of Unit 2.
